HAIRPIN.

Application led October 6, 1927. Serial No. 224,303.

The invention relates to a new and improved hairpin especially adaptedfor use in bobbed hair, although it may of course be used for securinghair of any Characteror length.

Bobbed hair in practically all of the present styles is so short thatordinary hairpins are not adequately retained by it and the use of suchhairpins is therefore annoying,

ic if not entirely impractical.

My invention consists in a hairpin in the general form of a spiral orconvolute, including portions designed to definitely and resilientlygrip short or long hair and retain I it in predetermined position, andat the same time retain the pin irmly in engagement with the hair, thedevice being preferably designed for application by a rotary movement.

Preferably also the device is made in the form of a symmetrical,doubleconvolute and in substantially dished form as later explained indetail. As otherwise described, the device is substantially a doublehairpin arranged in spiral or screw form for application by rotarymotion, each part of the double pin including closely-spaced resilientportions which grip the hair near the roots, and inner, larger or openportions in which larger bunches of hair are located in such manner thatthey lie flat or in normal position, these inner portions being alsodesigned to prevent inadvertent reverse movement or displacement of thepin. s., rl"he characteristics and advantages of the invention arefurther sufficiently explained in connection with the following detaildescription of the accompanying drawings, which illustrate certainrepresentative embodiments. After considering these examples, skilledpersons will understand that many variations may be made withoutdeparting from the principles involved, and I contemplate Atheemployment of any structures that are properly within the scope of theappended claims. v

Fig. l is a plan view of a hairpin embodying the invention in one form.

Fig. 2 is a side elevation.

Fig. 3 shows one of the pins in use.

Fig. 4 is a side elevation of a modiication.

The hairpin is preferably formed from a single piece of any suitablematerial, usually yieldable and preferably resilient, such as wire,Celluloid, bone or any other material commonly used for hairpins. Whenwire or like corrodible material is employed, it is usually coated witha protecting material. In the present specific example the pin consistsof a single piece of spring wire bent into the general form of asymmetrical, double spiral or convolute and including a centraltransverse member l which serves as a handle, the convolutes or spirals2 extending from opposite ends thereof. The device is preferably ofgenerally dished formation as best shown in Fig. 2; or it may bedescribed as a double conical convolute with each of the portions 2curving in a generally spiral manner about the center of the handle mem-'g ber l, and each also being deiected in the same direction away fromthe plane of said handle member. The end 3 of each member 2 ispreferably additionally bent downwardly and slightly outwardly toprovide an end or point which will easily enter the hair and then byrotary movement of the pin, grasped by the handle part l, hair is forcedinto the zones or spaces 4 between the adjacent parts of the twoconvolutes, with a screw or wedging action whereby the pin is firmlysecured in position and correspondingly securely holds the gripped hairin the position intended. While the spacing of the turns may varyconsiderably, it is usually preferable to arrange the adjacent portionsof the two convolutes quite close together, so that when a lock of hairis forced between them -by the wedging action of the flared end portions3, these adjacent portions of the convolutes will resiliently andtightly grip the hair near the roots. The inward portions of theconvolutes in cooperation with the central cross member, provide twoenlarged hair-receiving spaces 5 in which, after application of the pinin the manner just stated, relatively large bunches or locks of hair areaccommodated, these spaces being of suicient size to permit the hair tolie in a flat or other natural position, while at the same time theclosely adjacent portions of the convolutes grip other hairs near theroots, to firmly retain the device in position close to the scalp, sothat when properly applied practically no part of the hairpin is exposedor visible excepting possibly the central cross piece or handle portionl. The location of relatively large bunches or locks in the spaces 5usuall conceals the cross piece l and also serves e fectively to preventinadvertent reverse r0- tation or other displacement of the pin, sinceit is evident that any such tendency is resisted by the practicalimpossibility of the larger bunches'escaping from the spaces 5 throughthe narrower passages at 6 leading'tothe adjacent portions of the twoconvolutes.

From the preceding description it will now be understood that the deviceis, in one sense, a double hairpin, arranged in spiral or screw form,each of such double pins comprising a part of the central member and oneof the convolutes, these double pins acting cooperatively'to `firmlyretain the hair and to firmly retain 1 the device itself in position inthe manner previously described.

Fig. 1 3' suiiiciently explains 4one mode of use. The pin is shownyholding' a front lock in rear-ward position by rst engaging the pinwiththe Ifront-lock, moving it back to the desired position and thenengaging the pin with portions of the side hair, by 'rotary movement ofthe pin as suiiiciently-explained above.

Itis obvious that while the'pin is securely retained in position, whendesired it may easily be vremovedmanually` by reverse rotation.

Fig. 4 showsa modification in which gripping portions 5 of the spiralsor convolutes are-waved or crimped to provide an amplified grippingaction.

In eitherliiorm of the device the length of the spirallport-ions v2 may'evidently bevaried'considerably; that is these portions may belonger orshorter, without materially footing the general structural principle andmode ofl use.

I claim- .1. A hair pin of yieldable material comprising a centralportion serving as the sole handle member Vand extending-portionsdisposed on opposite sides of said central portion, said extendingportions being arcuate and substantially parallel to one another butspaced Vfrom one another to provide hair receiving spaces between saidextending portions, said extending portions terminating in'free endslrespectively spaced from one another and Ifrom said substantiallyparallel portions,saidfextending portions and said free `endsthereofbeing .dished relative to one another.

2. A- hair pin formed of longitudinally extending material, theopposite-portions of whichv are bent arcuately and downwardlyandsubstantially parallel to one another but spaced from one-'another toprovide hair receiving spaces between said arcuately bent portions, theportionV of sai'dmaterial interconnecting the arcuately bent portionsserving as the sole handle portion of the hair pin, said arcuately bentportions being dished rel.- ative to one another and terminating inoppositely disposed vfree ends extending arcuately from opposinglocations in the same direction.

3. A hair pin formed oit longitudinally eX- tending material,theopposite portions of which are bent arcuately and downwardly andsubstantially parallel to one another but spaced from -oneanother toprovide hair receiving spaces between said arcuately bent portions, theportion of said materia-l interconnecting the arcuately bent portionsbeing disposed in aplane and serving as the sole handle portion oi thehair pin, said arcuately bent port-ions being dished relative to oneanother and terminating in oppositely disposed free ends extendingarcuately trom opposing locations in the same direction, said free endsflaring' downwardly and outwardly relative to --said arcuately bentportions.

4. A hair pin formed of longitudinally extending material,.the oppositeportions of which are bent arcuately and downwardly and substantiallyparallel to one another but spaced from one another to provide hairreceiving spaces between-said arcuately bent portions, said arcuatelybent portions being crimped, the portion of said materialinterconnecting the arcuately bent portion serving as the-sole handleportion of the hair pin, said arcuately bent portions being dishedrelative to one .another and terminating infree ends extending fromopposite locations `ar cuately in the-same direction.

5. A hair pin formed of' longitudinally extending material,1the oppositeportions of which arebent arcuately and downwardly andsubstantiallyparallel to one another but spaced from one another to prov-ide hairreceiving spaces between said arcuately bent portitons, said arcuatelybent portions being crimped, the portion of saidvmaterialinterconnecting the arcuately: bent portion being substantiallyrectilinear and-serving as the sole handle portions of the hairpin, saidarcuately bent portions being dished relative to one another-andterminating in tree ends ext-ending from opposite locations `arcuatelyin the same direction, said free ends flaring downwardly and outwardlyrelative to said arcuately bent portions.

In testimony whereof-I have signed this specification this 1st day-otOctober, 1927.
